iThe-niachine base 1, hopper base 2, hopper 5, center support 6, separator member 7, separator member support 8.;lower feeding plungers 9, upper feeding plungersIO, conveyer 1-1, segment gear 12, P1111011 13, cap 1 1, drive shaft 15, earn membersltiyl? and 18, pulleys 19. 20 and 21, pinion 22; segment gear 23, conveyer 24:, pinionQL segment gear 26, segment gear shaft 27, support 28 and gears 29 and 30 constitute the principal parts and portions of our coating and forming machine.

Tlielrna chine base 1 is of the proper shape and size to support the machine andmounted on this machine base 1 is thehopper base member 2 by means of upright members 2 which issupported some distance above the machine base 1. This hopperbase Qispreferably acasting shaped as shown, provided with downwardly convergingcircular walls except on one side whichis flat. In this flat side'are provided apertures 2" and 2 shown best in -F 1 0fthe drawings. Theaperture2 is the intake for the center to be coated and the aperture 2 is for the exit of the surplus coating vided on the opposite side from the a erture 2 another aperture 2 shown in. ig. 6, adapted for the same purpose? 1 v Securedonthe uppeedge ofthis hopper base. member 2 is a hopper 3 conforming of the upper side of said base Fig. 2 of the drawings and provided with an inwardly extending flange 3 'adapted to engage the outwardly extending flanges 2 oil-the base member 2 and this hopper is secured thereto by means of bolts through the flanges 3 and 2 Secured in show-1i best in the base member 2 adjacent the flat side is the cylinder-member 4, by airtight fit at its bottom end and supported by means of a and there is also pro-' V of the drawings.

forming to the apertures 2 and2 the member 2 for the exit of surplus. It 1s also provided with an aperture conforming to the aperture 2 in the base member 2 for the intake of the centers and with two side apertures 4 for the inlet from the hopper of the coating substance'below the candy center and with two upper side apertures 4 which serve as inlets. for the coating substance above the candy center and this cylinder member 4 extends upwardly to approximately even with the top of the hopper member 3.

' .Reciprocably mounted in this cylinder member 4 is a plunger member 5 which is cylindrical in form and it is provided in its lower end with a cup shaped portion 5 which is adapted to form the upper portion of the outer surface of the coating and this portion 5 is provided with apertures 5 conforming to the apertures 2 and 2 for exit of surplus when he plunger is down. This plunger is reciprocated by means of an arm 5 which extends upwardly and engages the cam 17, secured to the shaft 15. Secured in the upper end of the cylinder at is a cap 14 which is provided with an upwardly. extending annular flange 14 in .which is revolubly mounted the separator support 8, which is provided with a pinion 13 on its upper end which is adapted to be engaged by the segment gear 12 secured on Q the main shaft 15-thus providing intermittent revoluble movement for themember 8.

. This member 8 is provided with a longitudinal slot 8* in one side thereof and mounted in this member 8- is the separator member 7 which is provided with a curved blade 7 7 on its lower end which is adapted to revolve against the inner surface of the portion 5 and separate the coating from said portion. 7 In the slot 8 is provided a lug 7 adapted to permit reciprocal movement of the member 7 relatively to the-member 8 but preventf torsional relative movement.

Reciprocably mounted in the member 7 is a candy supporting member 6 which is pointed. at its extended end and extends upwardly through the member 8 and is reciprocated by ;the cam 17 secured on the shaft 15. a I

Reciprocably mounted in the base member A 2 are the lower feeding plungers 9 by means of rods 9 which extend upwardly and are pivotally connected to the rocker arms 9" which are pivotally mounted on an axis 9 secured on an extended flange 14: of the cap member 14.

Pivotally connected to the opposite ends of the rocker arms 9 are rods 10 which extend downwardly and pivotally connect with the upper feed plungers 10 which are pivotally mounted at their opposite ends in a trough member 10 which is secured at its ends on the flange 3 of the hopper 3 and its sides extend around the cylinder 4. These rocker arms 9 are actuated by means of a rod 9 which extends upwardly through a support 9 and its upper end engages a cam 16, secured on the main shaft 15.

Mounted below the base member 2 and between said base member and the machine base 1 is a conveyer 11 which consists of an endless belt mounted on pulleys 21 and 21, shown best in Figs. 1 and 2. The pulley 21 is secured on a shaft 22 journaled in a bearing 22 and pivotally mounted on this shaft 22* are side supports 11 in the opposite end of which is journaled the axle for the pulley 21 and the free end of the supports 11 is actuated upwardly and downwardly by means of a rod 11 pivotally connected there to which extends upwardly and engages a cam 18 on a main shaft 15. Secured to the supports 11 is a transverse support 11 which extends upwardly and supports the belt 11 immediately below the lower side of the base member 2 to prevent the sagging of the belt with the pressure of the plunger member 5 in forming the coating on the candy center. Mounted on the shaft 22 is a pinion 22 which is adapted to be engaged by the segment gear 23 thus providing for the intermittent operation of the conveyer 11, this segment gear 23 is secured on a shaft 23*- and on this same shaft is secured a pulley 20, upon which is a belt 20* which connects with the pulley 19 mounted on the shaft 27. This shaft 27 is supported by a support 28 which also supports the shaft 15 and said shafts are operatively connected by the gears 29 and 30. The candy centers are fed into the aperture 2 by means of a conveyer 24: mounted on pulleys 2a and secured in connection with the shaft of one of said pulleys is a pinion 24 which is engaged by a segment gear 26 secured to a shaft 26 upon which is also secured a pulley 26 upon which is mounted a belt 26 which extends upwardly over a pulley 27, secured on the main shaft 16. This conveyer 24: is intermittently operated by the intermittent engagement of the segment 26 with the pinion 24 The operation of the machine is as follows: The hopper is filled with the coating substance and the candy centers positioned on the conveyer 24 and the operating parts are timed in the proper sequence to operate as follows:

The plunger 9 is moved downwardly in the hopper base 2, forcing a small quantity of the coating substance into the lower end of the cylinder 4 through the apertures and supported by the conveyer 11, then the candy center is moved into the cylinder "membere by means of the conveyer 24 members arethen moved downwardly simultaneously with: the upward movement plunger 5 is moved downwardlyin the cyl- 1 to any place desired, then the separator 7 through theaperture 2 and supported on said coatingsubstance, then the center sup? porting member 6 is moved downwardly piercing the candy center and the plunger of the plunger 9, forcing the coatingsub- Stance, into the cylinder above the candycenter through the apertures 4 then the is revolved inside the member 5?,separating the coating-- from the cup shaped member 5" by the gear member. '12 engaging th pinion 13. a

Then the plunger 5 and support 6 are 7 moved upwardly releasing the center and the cam 18jmovesl'thefree end of the supports 11 downwardly, then the segment engages thepinion 22 operating theconveyer, mov-. ing the finished product out of the-way andthe operation just recited is repeated.
